Astro Rumble Slot Review

Astro Rumble Slot Overview

Astro Rumble is a casino slot from Bullshark Games that invites players to test their driving (or flying?) skills in an intergalactic race against aliens. It's an entertaining thought to imagine that other species in the universe would be so keen on engaging in such a competition. While humans explored the field extensively with popular motorsports like F1, NASCAR, or rallying, would we expect intelligent inhabitants of distant planets to feel the same thrill of it? Whatever the case may be, that's the theme we'll be dealing with in this high-octane production, where Wilds, Multipliers, and Nitro symbols may charge our vehicle and let us cross the finish line first. The competition is fierce, and for a good reason, too, because the winner takes home the top prize worth 10,000x the bet!

Astro Rumble is a video slot from Bullshark Games with 5 reels, 4 rows, and 14 paylines. Players can choose their stake from a range of options, starting from a Min.bet of 0.1 up to a Max.bet of 100. The game offers a default RTP of 96.39%. Players will experience high volatility, with a max win capped at 10,000x the bet.

A tank filled with fuel and lightning-fast reflexes are essential for any race driver, just like valuable features are for players who strive to hit some big wins. The features of Astro Rumble are Pot of Nitro Symbols, Pot of Wild Symbols, Pot of Multipliers, Cosmic Boost, Rocket Race, Galactic Rush, and Feature Buy.

Astro Rumble Slot Information

The race takes place on a red, rocky planet, which could be Mars, considering there's another one resembling Saturn visible in the distance in the sky. A massive structure towers on the right, housing the audience waiting in anticipation of the great spectacle. On the ground, a stream of tarmac writhes between craters and disappears far in the distance, showing what challenge awaits the contenders. One of them is already waiting next to the grid in its floating space car, trembling with excitement about the upcoming race. On the steel-framed grid in the middle, paying combinations require at least 3 matching symbols to land on any of the paylines while using adjacent reels, starting from the leftmost one. Players can join the audience to watch this high-speed spectacle from any modern device, whether it's a desktop, a smartphone, or a tablet.

Regular symbols are split into two categories. Among the low-paying ones, there are four cards with characteristic emblems of clubs, diamonds, spades, and hearts, awarding 1x the bet for matching 5 on a payline. High-paying symbols include images of a stopwatch, a medkit, a shield booster, an energy booster, and a Nitro booster, rewarding players with prizes from 5x to 20x the bet for a complete combination. In addition to the regular symbols, there are Wilds depicting a purple alien and Scatters appearing as a golden trophy.

What is the max win in the slot Astro Rumble?

You can win up to 10,000x the bet.

What features are available in the slot Astro Rumble?

The features are Pot of Nitro Symbols, Pot of Wild Symbols, Pot of Multipliers, Cosmic Boost, Rocket Race, Galactic Rush, and Feature Buy.

Pot of Nitro Symbols

One of the pots (red) visible above the grid may award a random number of the top-paying Nitro symbols. Possible amounts are 2, 3, 4, 5, 6, 8, or 10.

Pot of Wild Symbols

The second pot (purple) is responsible for adding Wild symbols in random positions on the grid. Possible amounts are 2, 3, 4, 5, 6, 8, or 10. If a Wild lands on top of another Wild already on the board, it adds a point to the Pot of Multipliers.

Pot of Multipliers

The third pot (orange) may award multipliers to random symbols on the grid. The possible amount of affected symbols is 2, 3, 4, 5, 6, 8, or 10, while the possible values are 2x, 3x, 4x, 5x, 10x, 25x, 50x, or 100x. If more than one multiplier participates in the same payline win, their values are added together. Similarly, when a multiplier is added to a symbol that already has a multiplier, they are combined.

Cosmic Boost

The feature can trigger randomly during the base game and activate one, two, or all three pots simultaneously.

Rocket Race

Landing 3 or 4 Scatters during the same base game spin awards 8 or 10 free spins, respectively. Before the game starts, a random pot receives a boost of 2, 3, 4, or 5 points. Scoring 2, 3, 4, or 5 Scatters during the bonus awards 2, 3, 4, or 5 extra spins. Throughout the Rocket Race, Nitro and Wild symbols landing on the grid are collected in their respective Pots. Analogically, any symbol may land with a multiplier, in which case a point will be added to the Pot of Multipliers. Values stored in the pot determine how many Multipliers, Wilds, and Nitro symbols will be added to the grid on the following free spin.

Galactic Rush

Landing 5 Scatters in the base game activates 12 free spins. This bonus maintains all the rules of the Rocket Race bonus, but it begins with all Pots receiving a boost.

Feature Buy

Astro Rumble offers several options to boost the base game spins or trigger features instantly for a set price.

3x = Bonushunt Featurespins with a 5-times higher chance to trigger free spins.

50x = Cosmic Boost Featurespins, guaranteeing the activation of at least 2 Pots.

100x = Rocket Race bonus with 8 or 10 free spins.

300x = Galactic Rush bonus with 12 free spins.

Astro Rumble Slot Conclusion

We must admit that aliens and racing is not a combination we see too often in the online slots industry. There are some games that tackle the subject in their own unique way like Wrigley's World by Red Tiger, but it's generally a niche fusion. Still, a setting like that provides plenty of opportunities to create a truly dynamic experience because what could result in a higher adrenaline rush than racing powered by cosmic energy? Unfortunately, the creators at Bullshark Games did not manage to capture the high-octane atmosphere with the design and effects implemented into the theme. For a scene that's supposed to overflow with motion and overall liveliness, it's all rather static and does not convey the thrill of watching vehicles speed recklessly on a track. The only movement, aside from what's happening on the grid, is the little alien trembling excitingly in its space car. Otherwise, the quality of the design is quite eye-pleasing, comprising sleek, futuristic symbols and nicely synced animations contributing to a smooth gameplay experience.

Under the hood, Astro Rumble may feel like a relatively straightforward mechanism, although it can pack some punch during the bonus round. In the base game, the only opportunity for some more significant wins is the random trigger of Cosmic Boost which can activate up to 3 Pots to award Wilds, Multipliers, and top-paying Nitro symbols. Even though it's a single activation, up to 10 units of each of the features can hit the grid for some decent payout. The bonus round offers a solid improvement of that feature, turning all Pots into progressive meters, accumulating their respective symbols spin by spin. That, in turn, massively boosts anticipation as free spins progress, allowing for increasingly higher amounts of those valuable icons invading the grid. Considering it's a 5x4 setup, having a 10+ value on the Wild counter, for example, already promises solid wins until the feature ends. Combine that with a bunch of top-value Nitro symbols and multipliers up to 100x and there's plenty that can surprise you on every spin, along with a max win of 10,000x the bet.

Astro Rumble does a great job of maintaining anticipation during its powerful bonus, although misses some motion and energy in the supposedly dynamic theme.
